Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
Is the check engine light on or does it ever come on? Thanks.
This is a common symptom of a failing fuel pump. They will work when cold and then cause a stall when warmed up but restart once cooled down without turning on check engine light. A quick test is to see if it runs on starting fluid next time it won't start, if it starts this verifies problem is fuel related and you will want to replace the pump. This will be around a $400 job at a shop. Let me know if you have more questions or if you would like replacement instructions. Thanks.
That would mean no spark which is most likely caused by failing ignition module or ignition switch. Next time problem happens check to see if pink wire going to ignition module has good power while trying to start, if not replace ignition switch. If it has good power then I would replace ignition module. Let me know if you have more questions, thanks.
That would also fit the no spark symptom, while trying to start you are flooding engine. Let me know if you have questions, thanks.
If it won't start on starting fluid then that verifies a spark problem. Only other thing that would cause a no start is loss of compression but no reason that would be intermittent. Let me know if you have more questions, thanks.
That is correct, it should have at least 11v while trying to start. Let me know how it goes, thanks.
Yes it could, so could the crankshaft position sensor but without capable scantool to monitor crank sensor it will be hard to tell.
You would need to use a scantool to monitor signal or try to use a multimeter to monitor signal and compare to when it does start. Let me know if you have questions, thanks.
Good to hear, let me know how it goes or if you run into more questions. Thanks.
No, it is pretty straight forward. Worst case there may be a couple rusty bolts but still shouldn't cause too much of a issue. .
